Pros and Cons on Recycling

• PROS: Reycling lowers costs because materials are made from reycled products.


• Recycling avoids the cost of moving garbage barges and incineration.
  Reycycling helps the earth because we are using old materials rather than depleting the earth stock.

CONS: Costs money becuase of the transportation and processing costs.
Uses money because of the machinery needed in order to recycle materials.
Recycling also uses energy and can also pollute the earth because of the fumes produced by incineration and the machinery they use.
